Mitsubishi Montero Sport key types & programming facts
2000–2004 Mitsubishi Montero Sport models for the U.S./Canada market use a separate keyless entry remote that can be programmed via an onboard procedure using the vehicle’s diagnostic/data link connector. Programming generally requires entering a special mode through the DLC, then registering each remote by pressing the lock button a specified number of times within a time window. Cutting or replacing the mechanical ignition key itself is a standard key-duplication process; available sources only document onboard procedures for the remote portion, not a transponder chip system.
Key types used on the Montero Sport:
- standard metal key with separate keyless entry remote (no transponder chip documented) (2000-2004)
Common fob FCC IDs: E4EG8D-522M-A — check the back of your fob; we confirm the exact variant on site.

How we validate this guide
Year coverage comes from our consolidated vehicle programming dataset. Route-level programming status is reviewed against internal route sheets and available manufacturer, security-access, and professional tool references. Exact button sequences are marked source-verified only when we have year/equipment-specific support; where a year is labeled “route verified, steps vary,” we confirm the exact fob, trim, and prompts before programming.
